Bypass Valve / Blow Off Valve

The ST165 and ST185 did not come equipped
with an air bypass valve for turbo protection. Due to the lack of
spacing and customer support kits were never created for these
vehicles. Here is the information about the universal valves
available so that you may create your own system. If you are buying
a Blow Off Valve, regardless of brand, be sure to get the universal kit
unless otherwise specified. For more information about what a Bypass
Valve or Blow
Off Valve is, visit the BOV FAQ. Click for
